Restore silent operation to your bass pedals. If you hear a click when you press a bass pedal down it is probably the spring steel strip making direct contact with the metal plunger that keys the pedal tones. With use the felt piece between these two items wears out and a hole the size of the plunger tip is created.

This felt strip is designed to replace both the original full length cloth strip in the very early consoles (Model A, BC, BV, etc.) and the individual felt loops in later units (B-2, B-3, A-100, etc).
